The research relevance is determined by the diverse constitutional approaches adopted by countries worldwide to address the critical issue of succession in the event of concurrent vacancies in the positions of President and Vice President. The study aims to correctly determine the appropriate acting presidency during extraordinary situations to ensure the continual rule of government. A doctrinal research method alongside a comparative constitutional approach to explore the constitutions of various countries. The study determined that there are legitimized and bureaucratic actors who compete with each other to become acting presidents when the positions of President and Vice President are vacant in various parts of the world. Countries that use legitimacy actors generally use the Speaker of the House of Representatives/Senate (legislative) as the acting president, while countries that use bureaucratic actors generally use ministers (executive) as the acting president. Legitimate actors are the officials to become acting presidents due to their capabilities to ensure stability based on democratic legitimacy stability, backed by votes. The practical value of this article is that it can be a source of knowledge for constitutional drafters when amending/changing the constitution because it has aggregated the arrangements for presidential duty executors from world constitutions and contributes knowledge from Indonesian experience that can be considered as material for discussion of constitutional amendments/changes.

Rethinking'Res Judicata Pro Varitate Habetur'in Indonesian Judiciary

This research explores the principle of" Res Judicata Pro Varitate Habetur," a legal doctrine asserting that a judicial decision with legal authority must be considered correct and binding. Focusing on its application in the decisions of the Constitutional Court (MK) and the Supreme Court (MA) of Indonesia, the study emphasizes the authority and differences in the finality of their rulings. It proposes a conceptual update to" Res Judicata Pro Varitate Habetur" aimed at enhancing public access to legal truth, considering the need to balance legal certainty with judicial system improvements. The research employs a Juridical-Normative method, incorporating conceptual, juridical, and case study approaches. The conceptual approach underscores the importance of understanding legal concepts as a preliminary step in analyzing legal norms. This approach involves the analysis of legal texts, the objectives of the law, and the relevant legal system. The juridical approach involves understanding and analyzing law by referring to the applicable written norms, while the case study approach involves analyzing court decisions or relevant legal cases. The findings highlight the role of this principle in maintaining legal certainty, and suggest that its conceptual update could enhance public access to legal truth and contribute to legal thought on future judicial system reform.

This normative juridical research, utilizing statutory and conceptual approaches, aims to explore future policy models for the legal protection of children within the juvenile criminal justice system in Indonesia. Acknowledging various challenges in the current system, the study emphasizes the necessity of reforming policies to ensure legal certainty and justice for minors in conflict with the law. The proposed model advocates for a'pure decriminalization'approach, which involves removing the punishable nature of certain criminal elements committed by juvenile legal subjects. This model is complemented by a protection policy that underscores preventative measures to decrease the involvement of children in the criminal justice system. A significant emphasis is placed on integrating technology into the system to enhance efficiency and security, thereby safeguarding children's rights more effectively. Additionally, the research highlights the need for increased inter-agency and cross-sectoral cooperation within the legal structure (police, prosecutors, and courts) to create a more coordinated and holistic approach in addressing juvenile justice issues. The findings suggest that these strategic efforts can contribute significantly to the improvement of procedural law applications for children, ensuring their human rights are not violated in future legal encounters.

Based on the issues related to the lease of reward land between the village chief and a private party that exceeds the chief's term, this paper aims to analyze the legality of the lease agreement for reward land between the village chief and a private party that extends beyond his term of office. In this paper, the researcher uses a normative juridical method, along with a legislative and case study approach. Then, with this analysis, the researcher can address the raised issue about the legality of the lease agreement for reward land between the village chief. From these issues, it can be concluded that the legality of the lease agreement for reward land between the village chief and a private party is regulated in Permendagri Number 1 of 2016 concerning the Management of Village Assets, with the maximum lease limit for reward land being a maximum of 3 (three) years. If there is a lease agreement for reward land between the village chief and a private party that exceeds the chief's term of office, then the agreement is legally void.

As the holder of power in the administration of government based on the constitution, the president has set a new policy, namely regarding the mechanism for granting presidential approval to draft regulations of ministers or heads of institutions. With the birth of this arrangement, every policy of ministers or heads of institutions with certain criteria must obtain presidential approval before being determined. The mechanism carried out after harmonization has indirectly obscured the stage of forming laws and regulations that are prevalent today. With juridical normative research methods that use statutory, conceptual, and historical approaches, it was found that the arrangement for granting presidential approval actually brought back classic problems. The arrangement is harmonized with other regulations. There is vagueness in sentence formulation, use of words, terms, or phrases, which causes multiple interpretations. The arrangement also comes out of the national policy framework related to simplifying regulations promoted by the president himself. In its formation, there is also the possibility of the influence of bureaucratic political practices or competition among state administrative work units in finding alternative solutions to problems that arise in society.

In a democratic rule of law like Indonesia, delegated legislation emerges as a necessity. Unfortunately, Article 8, paragraph (1) of Law Number 12 of 2011 concerning the Establishment of Laws and Regulations, in conjunction with Law Number 13 of 2022 concerning the Second Amendment to Law Number 12 of 2011, fails to articulate a clear hierarchy of delegated regulations. Employing a juridical-normative research approach encompassing statutory, historical, and conceptual dimensions, this study sheds light on the prevailing legal vacuum. The research reveals that a staggering 24,052 regulations at the level of Ministries, Agencies, and State Institutions run the risk of overlapping and becoming subject to judicial review in the Supreme Court. The definition of Delegated Legislations in Indonesia, as interpreted herein, is confined to regulations whose legal construction is executed by the executive, as long as formal legal norms continue to confer the authority of delegation in the legislative domain to implement superior regulations. This paper identifies three distinct models governing the structuring of Delegated Legislations within the hierarchy of laws and regulations in Indonesia. These models include the Hierarchical model based on the legal foundation of institution formation, the Hierarchical model based on the position of the institution, and the Hierarchical model based on the source of delegated authority in forming rules. This nuanced exploration seeks to address the complexities surrounding delegated legislation, aiming to provide clarity and coherence within the Indonesian legal framework.

This paper aims to study the construction of an appropriate legal basis for a state of law in responding to the Covid-19 emergency. As a state of law, Indonesia has been making many regulations at both central and local government levels. The regulations vary, ranging from Government Regulations in Lieu of Law, Ministerial Regulations, Ministerial Decrees, and Joint Decrees of Ministerial Instructions, to the Regulations of Regional Heads, and these regulations have led to overlapping regulations. With normative-juridical methods, the prescriptive technique was used to further analyze the problem and find a new concept of the construction of an appropriate legal basis in responding to the Covid-19 emergency. The research results show that, juridically, the use of non-legal products such as Ministerial Instructions and Circular Letters issued by ministers during the Covid-19 emergency in Indonesia has fulfilled the procedural aspects of law-making but not the substantive ones regarding the curbs restricting people’s social activities. This research recommends that the construction of a legal basis intended to respond to a state of emergency should simultaneously meet both procedural and substantive aspects

This study examines the Legal Implications of using Ministerial Instruction Instruments as the Legal Basis for the Implementation of Restrictions on Community Activities During the Covid-19 Pandemic. As is known that during this pandemic, the Government made many instruments in the form of Ministerial Instructions to respond to the transmission of Covid-19 in the form of the Implementation of Restrictions on Community Activities. In fact, these instruments are not laws and regulations so they are not binding in general, let alone limit human rights through restrictions on the right to activity and threaten criminal sanctions. The Covid-19 Pandemic Emergency was also responded to excessively by several Ministries by issuing rules at the respective Ministry level, both in the form of a Joint Decree (SKB) and a Decree. In fact, among these instruments overlapping authorities, for example, related to the distribution of social assistance (bansos). In this case, there are legal problems related to the implications of the use of the Ministerial Instruction Instrument as the legal basis for the Implementation of Restrictions on Community Activities During the Covid-19 Pandemic. The problem arises due to the legality and binding force of the Ministerial Instruction and the impact of the implementation of the Ministerial Instruction on the protection of Human Rights. Through the normative juridical analysis research method, this research will reconstruct the legal basis in accordance with the principles of the state of the law in the event of a pandemic emergency so as not to reduce human rights.

After the first amendment to the 1945 Constitution, there was a shift in power to form laws from the President to the DPR. The power of the DPR to form laws is shared with the President because each bill is discussed jointly by the DPR and the President for mutual approval. The joint approval of the DPR and the President is the binding point for the two state institutions that produce material laws. However, there are several bills that have been mutually agreed with the DPR and the President that have not been signed by the President. After a period of thirty days has been lapsed, the mutually agreed Bill by the DPR and the President shall become Law, even without the ratification of the President, and must be promulgated. This phenomenon raises question of why the President does not ratify the Bills he has approved. This research is a normative research with a statutory, conceptual, historical and comparative approach, which is expected to provide coherence and continuity to constitutional theories, so that the process of forming laws with outputs at each stage to be with more measurable results.

The function of the Indonesian Constitutional Court as the guardian of the constitution is mainly conducted through the judicial review authority. From 2003 to April 2021, the Constitutional Court has received and decided 1392 petitions over judicial review. In its dictums, the Constitutional Court often declares conditionally constitutional or conditionally unconstitutional (conditional decision). The conditional decision is a decision of the Court that declares the reviewed norm conditionally constitutional or unconstitutional. The norm is constitutional if interpreted according to the Court interpretation, or the norm is unconstitutional if interpreted in specific ways. This research investigates the criteria of judicial review decisions that declare conditionally constitutional and conditionally unconstitutional according to the characteristics of norms of the law reviewed. The analysis was limited to the Court decisions from 2003 to 2017. The research result indicates that distinguishing characteristics of norms reviewed have no correlation with conditionally constitutional or conditionally unconstitutional options. Conditionally Constitutional Decision was used by the Court before replaced by Conditionally Unconstitutional Decision due to the weakness of decision implementation. For conditionally unconstitutional decisions are connected to the substance of the decision, creating a new norm that replaces, limit, or elaborate reviewed norm. The conditional decision is still required due to the following three aspects: enforcement of the supremacy of the constitution, the presumption of validity, and strengthening the execution of Constitutional Court decisions.
